Don't think so. I agree with you, though. The floppy music is way better.

I remember discovering that there was a CD talkie version of Gob3 and getting all excited, but alas it seems that none of the Coktel Vision CD versions of their games have even remotely the same soundtracks as their floppy counterparts. Bizarre. I was surprised when I played the floppy version of Lost in Time for the first time and was treated to wildly different music than the CD-ROM edition, which is what we always had.

Only way to do it would be to rip the redbook audio track as WAV, go in and edit the giant track and replace the exact spots where there is music with digital recordings of the floppy Adlib soundtrack. But then, the different levels might repeat different tracks than the floppy version does so it might not be able to be 100% exact.
